how much should a lead cost for different GEOS in crypto forex vertical?

Hey guys
help me to understand approximate cost for the lead I should aim for

I understand that it depends on a lot of things, like sources, funnels, filters
but still i wanna know at least from ... and to .... for different geos

thanks in advance
